Dual Battery System

A dual battery system is a setup where two batteries are used in a vehicle instead of the usual one. This is often done to provide additional power for various accessories or to improve overall reliability and safety.

There are two main types of dual battery systems: isolator and parallel systems.

An isolator system uses a device called a battery isolator to separate the two batteries so that they do not interfere with each other. This is often used in RVs and boats where one battery is used for starting the engine and the other battery is used for powering appliances.

A parallel system connects the two batteries together in parallel so that they both contribute to the overall power of the system. This is often used in off-road vehicles where additional power is needed for winches, lights, and other accessories.

There are also several different types of batteries that can be used in a dual battery system, including lead-acid, lithium-ion, and AGM (Absorbent Glass Mat) batteries. Each has its own advantages and disadvantages in terms of cost, weight, and performance.

If you are considering a dual battery system for your vehicle, it is important to research and plan the setup carefully. This may involve consulting with a professional installer to ensure that the system is safe, reliable, and efficient.
